Specification of Letters Patent.

Application filed March 25, 1912.

Patented Nov. il 8,1913.

serial No. 685,989.

To all `whom it may concern Be it known that I, Prune D. BUNDY, a citizen, oit' the United States, and a resident oit h/fount Vernon, in the county o't' lose'v and State of.' Indiana, have invented certain new and use'tul improven'ients in Well- Diggers rFools, oit' which the following` is a specification, reference being had to the accompanying drawings.

This invention has relation to certain new and useful improvements in `well diggers tools, and my invention comprises a gral plingtongs by means oit which the small rocks and stones displaced by the drills and angers can be readily and expeditiously removed from the bottom oi the well.

lVith these and other objects in view, the present invention consists in the eo111bina tion and arrangement oi parts as will be hereinafter more fully described and finally pointed out in the appended claim, it being further understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

lfn the accompanying drawings formingl a part of this specification and in which like numerals of reference indicate similar parts in the several views: Figure 1, shows a view ot' my `grappling' tongs in an open position at the bottoni oit' the well. Fig. 2, shows a sectional view with the tongs in their closed condition. Fig. 3, is an end view. Fig. 4t, is a section on line 4, 4L of Fig. 2.

In the boringj)` of wells, small stones and rocks are displaced by the drills and angers. The boring,` tools not beine' so constructed as to bring these to the surface, they roll around at the bottom of the well, until they finally interfere with the proper operation of the drill or auger. A special tool is then required to remove these loose stones and rocks and in my present invention I provide such a tool, which can be positively and expeditiously operated to clear the well o3t' all loose rocks and stones.

In carrying out the aim of my invention I employ a tubular sleeve l, of any suitable length having its lower end threaded to re eeive the interiorly threaded coupling 2. A tubular collar 3, is screwed into this coupling as clearly shown in Fig. Q. The diameter of the collar 3, is considerably greater than that of the sleeve 1, as shown.

Fixed to the lower end of the collar 3, by

means of the rivets S, is the fork 4L, including' a plurality of lines o, and a straight tang t3. .fis shown at the end o't the tang' (i, is loca ted a stop collar 7.

Secured to the collar 3, at a pointI opposite the fixed 'fork member 4, are the ears 13, secured by means of the rivets 14. These ears carry a pivot piu 12, to which is pivotally secured the fork 5', having the tines 9, tane; l0, and the stop collar ll, this con struction being clearly shown in Fig'. 2.

Slidably held within the sleeve l, is the operating' rod 1T, the lower end of which is threaded as shown at 1G, so that the same can be screwed `into the yohe 15, which has two openings as indicated in dotted lines iu Fig. 2, to receive the fangs G and 10. ln reciprocating' this operating rod 17, the 'fork member '10, can be carried away or toward the fixed fork G. At its upper end the operating rod 17, has a coupling 1S, receiving the eyebolts 19, to which is secured the operating' strand 23.

Secured to the upper end of the sleeve l, is the stop collar Q0, held yby means of the set screw 21. This collar is provided so that the carryingl strand 22, can be secured to the sleeve l. As shown in F ig. 1, the carrying strand 22, is in line with the moving fork l0. The carrying strand could be easily shifted to the opposite side to bring,- the same immediately above the fixed 'fork (i. As this 'forli member (i, is fixed. the same in being lowered when the strand Q2, is imincdiately above the same will engage the side of the well. Then it is desired to grapple the stones, the operator raises the yoke 13, by means ot' the operating strand 23, to carry the fork member 10, toward the fork member 6. The tool is then raised and emptied. The operation is of course, repeated until all the loose stones have been removed from the well.

It is, of course, understood that tools embodying my invention may be made of various sizes.

The tool is simple and inexpensive in construction and both durable and eflicient in operation and the device further may be operated with ease, accuracy and despatch to remove stones and rocks from the bottom of the well.

Having thus described my said invention, what l claim as new and desire to secure by United States Letters Patent is:

A device of the character described, having in combination, a sleeve, a coupling secured to the lower end of said sleeve,V a collar extending from said coupling, a fork fixed to the lower end of said collar having a plurality of tines and a straight tang, an ear secured to said Collar opposite said fork, a fork having a plurality of tines and a straight tang pivoted to said ear and arranged for co-aotion with said fixed fork, a yoke sliding upon and guided by said fixed fork tang and engaging said pvoted fork tang and an operating rod guided within said sleeve and secured at its lower end to said yoke, each of said tangs having a stop shoulder to limit the upward movement of said yoke.

In testimony whereof ll aiiix my signature,

in presence of two witnesses.
